To (all iii/tom it may concern Be it known that I, Josnrn Mnmncnn, a citizen of: the United States, and a resident. of Paia Maui, Territory of Hawaii, have invented certain new and useful Improvements in Canefiugar Mills, of which the following is a specification.

This invention relates to improvements in cane sugar mills and more particularly to an improved intermediate cane chute for tranz-iferring or conveying, the bagasse from one mill to the other.

l 'lcretofore, in the art of sugar mills, devices have been constructed for conveying the ba-gasse from! one mill to the other, these devices being in thenature of endless conveyors employing: chains, sprockets and bars or slats connecting the chains to carry the bagassc from one mill to the other between. adjacent inacerating rollers of the mills. scrapers being employed at each end, but these devices having been found objectionable due to the constant delays from breakage and injury to the parts at a consider: ble cost of production and upkeep or maintenance. Eliort has also been made to push or use pressure. in carrying the bagasse from one mill to the other but is objectionable and the devices found inefficient and discarded, owing to the fact that the enormous pr ssure of the bagasse in being pushed from one mill to the other, bent the chute and .bars of steelvforming reinforcing means for the same. Such a chute W s curved and associated with znacerating sr 'apers but resulted in the material packing: up therein and IGIlilGllflg operation 1m- The present invention has for its pbjects to provide an improved chute by which the baggassc may be properly pushed or conveyed from one mill to the other. without injurv or distortion from the pressure, as vvcll as obviating; the necessity of employin; a conveyor of the slatted and belt type and, eliminating the large number of complicated parts and expensive construction together with all movable parts employed in the old chain type of conveyor, and thereby avoiding constant annoyance from the necessity of repairs, reducing the cost of construction and installation, as Well as maintenance and upkeep, eliminating all rollers and other movable parts.

it am aware of prior Patents Nos. 1,191,826, 1,209,618 and 1,204,314, as Well as structcd so as to facilitate cleaning; when the mill is shut down at the end of the V/Q or at any other time.

I obtain these objects by the device illus trated and other and further objects of my invention will become readily apparent to persons skilled in the art, from a consideration of the :l.ollowin; description, when taken in conjunction with the accompany inc drawings, in Which:

Figure 1 is a side elevation. showing the improved intermediate cane chute as ap-- plied "to a sugar cane mill and in transfen rin the bagasse from one mill to the other between the macerating rollers thereof with which scrapers are employed,

Fig. 2 is an enlarged fragmentary vertical sectional view of the discharge end of the chute, and

Fig. 3 is a transverse sectional view taken on the line 3--3 of Fig. 2.

Referring to the drawings in detail, in which like reference characters designate corresponding parts throughout the several views. the numeral designates a sugar cane mill having the usual macerating rollers and 11 an adjacent mill of a plurality or series properly spaced apart to inacerate the cane or like material, the-expressing rollers thereof being designated at 12. The conveying apparatus is arranged between the adjacent mills for the purpose oi: feeding the bagasse from one will to the other and in the prcsent instance the improved chute is designated generally at 13. This chute is oppositely inclined between the dis charge end of the preceding mill. and the feed end of the succeeding mill, and includes a bottom plate 14 arranged at an angle of from to lf preferably ii-5 from the horizontal at the feed end of the succeedin;- mill, said plate being: disposed in aninclined position and havinginclineoi and joined therewith to extend in anippp'osite ,directioma bottom piate'lfi, which like the Kil ilti

"lhe bagusse is furthermore delivered upwardly or in an upward direction with a gradual taper and no curves or a completely closed chute is employed or necessary and therefore attendant objections to such devices ure overcome. The material or bageese slides down the discharge chute or bottom plate without any assistance and the inaccruting water is applied as the material comes out of the chute on its downward movement. That is there is no pressure on the bugasse as the chute is gradually tapered end there is only it pressure tending to shove the material from the discharge roller into the receiving mill, thus avoiding all movable parts or u:

"serrations in the design of the mill with obvious advantages manifest to anyone acquainted with the art. Also, by reason of the constructionprovided there is considerable clearance beneath the chute and this is en importnntfactor in the operation of the mills. It is also to be noted'thut the top portion. or cover extends at an angle 10 from 31) to 35 from the horizontal, preferably 35 when the bottom plate 15 is disposed at an angle of 30 from the horizontuli causing the covered portion oi the chute to be Wider atits discharge end than at its receiving end adjacent to the scrapers, so as to free the pressure which would otherwise be attendant in the conveyance of the bagasse.

in view of the foregoing, it is thought v that the operation oi": the device wiil be readily understood and in view of the sim plicity and precticel value, that it will commend itself to those skilled in the art.

Having thus described my invention, whet 15 I claim isz-- 1. An intermediate feed chute for sugar mills comprising oppositely inclined portions disposed at different inclinations, said portions being flat and means for supplying macercting fluid at the apex of the chute.

2. A chute oi the character described for disposition between spaced mills of a cane sugar mill or the like comprising oppositely sloping bottom portions, side portions there- 12! for adapted to conform to the rollers of the mill, the bottom portion at the receiving side being provided with a. removable cover and the bottom portion at the discharge side of the chute being uncovered, end means for supplying macerating fluid at the apex por- .tion' of the chute whereby the bagasse may expand unrestrained by the cover.

prising atrough-like structure open at the stop ,and'having oppositely inclined bottom portions, the receiving side being otless inclination than the discharge side, a cover at (the receiving end portion of the chute, said tapered formation and be,-
